One of the regular early morning swimmers at our local pool had been absent for a few days and we have now found out that she has taken her own life. Sadly, it's the third suicide in as many weeks in our relatively small community - the first was a young man in his twenties, and the second in his mid-thirties. Families and friends have been left confused and devastated, and we are all asking ourselves what we missed and how we can try to make sure this doesn't happen again. It's made me think. Sometimes there are obvious signs and reasons for suicide but often it seems to come out of the blue. Is it becoming more common, or is it just that we are more open about it now? Is there something about modern life that is making more people feel they have no choice but to end it?
